. mixture of air and steam to the inlet manie This invention relates to an apparatus to be used in combination with internal combustion engines, and particularly to an apparatus which not only reduces the opmntityl of fuel consumed but also prevents carbon formation' when low gravity fuels are employed. p

One of the objects of the present invention is to provide means for introducing a fold of an internal combustion engine, and in conjunction therewith to provide a valve whereby the quantity ot' said mixture admitted may be regulated. Another-object of the invention is to provide a simple, easily applied Iheater for generating the steam.

The invention consists of the parts and the construction and combination of parts as hereinafter more -ully described and claimed, having reference to the accompanying drawings, in Which- Figure 1 is a side elevation of an internal combustion engine, showing the application of the invention. Fig. 2 is an enlarged, central, vertical section of the mixer.

Referring to the drawings in detail, indicates the cylinder head of an internal combustion engine, 2 the cylinders, 3 the exhaust manifold, and rthe inlet manifold. The type of engine employed in the presentinstance is Water-jacketed, as shown at 5, and the cooling water employed is eirculated inthe usual manner through a radiator 6. Extending through the exhaust manifold is a pipe i" which serves the function of a steam generator. and connected with one end of said pipe, by means of a union 8,

, is a goose neck 9 and connecting` said goose neck with the jacket of one of the cylinders is a pipe. 10 which is provided with a reguating valve 11.

Suitably supported on one side oi the rengine' is a casing 12, interiorly of which is formed a combination trap and mixing chamber 13 which is connected with the Specification of Letters Patent.

pipe 7 by means `of a i e 14. This pipe is inclosed by a second gige 15 which forms a jacket about same and which also permits a certain amount of the exhaust gases to escape at the open end indicated at 16. The opposite end of pipe 15 connects directly with the exhaust manifold and thereby forms a communication which permits a part of the exhaust gases to escape around the pipe 14 and out through the open end 16; this jacket being merely provided for the purpose of retaining,r the pipe 14- as hot as possible to prevent 'recondepsing of the steam generated in tite pipe' Connected with the lower end of the casing 12 and-communicating' with chamber 13 Patented May 14, 1918.

is an S-shaped trap pipe 17, the function of which will hereinafter be described, and connecting the chamber 13 with the inlet manifold is a pipe 18 upon which is mounted a valve 19 which may be opened or closed from the dashboard. by means of a rod 20 and a handle extension 21.

In actual operation, with the valve 11 slightly open, a certain amount of Water is permitted to enter the pipe 7. This is constantly maintained at a high temperature While the engine is running andv therefore constantly causes the Water to turn into steam before it escapes through pipe 14 into the trap and mixing chamber 13. Any Water which may have condensed or passed through the pipe is here caught by an inclined screen 22 Which causes it to drain down to one side and collect in the bottom of the I chamber 13, as shown in Fig. 2. The steam admitted is permitted to escape through the connected pipe 18 and Will thus enter the manifold through the valve 19, the quantity admitted being controlled entirely by the opening of said valve. ter collected or trapped in chamber 13 Will never assume a higher level than the highest The amount of Wav point in the trap pipe '17. It is, therefore,l

in the pipes 14, 7 and 10. The Water fromv the jacket 5l is in this manner raised by suction to the steam generator and is also constantly Withdrawn fromsame in the form
